New: the Orange Line pack — 12 levels with the paint station. White dots are neutral and only get their color at a painter. DotTracks is a calm, minimalist train track puzzle — draw the rails, mix the colors, and route every train home. Free, no ads, no signup. Each level gives you a grid, a few colored trains, and matching stations. Your job: draw tracks so every train reaches the right station. Start with simple straight paths. Soon you'll be merging trains at crossings, splitting them at junctions, repainting them at paint stations, and routing three colors through the same shared corner — one wrong tile and a blue train ends up at the red dock. A logic puzzle that's easy to learn and tricky to master. • hand-crafted levels across four packs (more on the way) • Merge, split and mix train colors at crossings and junctions • Repaint trains at paint stations — white trains are neutral until colored • Rate the difficulty of every level you solve • Free and ad-free: no account, no email, no interruptions • Works offline — built for short breaks, train rides, and the quiet 5 minutes before sleep • Available in English, German, French, Italian and Spanish Your progress is backed up automatically under a random ID — no personal account needed.
